A scoping review of interventions to supplement spoken communication for children with limited speech or language skills

Parents' perception on the use of augmentative and alternative communication by children with complex communication needs in Malaysia

PURPOSE

Children with developmental disabilities who have complex communication needs (CCN) frequently need to use augmentative and alternative communication (AAC) to communicate effectively and efficiently. Speech-language pathologists (SLPs) often work closely with parents and other professionals when deciding on the best AAC system to introduce to these children. This study aimed to describe the use of AAC by children with CCN in Malaysia as reported by their parents.

MATERIALS AND METHOD

An online survey distributed for this study was completed by 235 parents.

RESULTS

Most of the parents of children with CCN who participated in this study reported that their children used low-tech AAC systems. A majority of respondents were satisfied with their child's AAC system. Parental satisfaction was positively associated with the frequency of use and whether the use of AAC helped parents understand the child better. Challenges reported by parents when using AAC and the reason some families abandoned the use of AAC were similar. Examples of challenges include parents having limited time and the child lacking the motivation to use the AAC system.

CONCLUSION

The findings of this study suggest the importance of SLPs actively involving parents in the selection of their children's AAC system so they are agreeable with the system introduced and continuously supporting children and their families to encourage and sustain the use of AAC. Implications for rehabilitationSpeech-language pathologists (SLPs) can create communication opportunities for the child to use augmentative and alternative communication (AAC) and experience success, teach parents how to incorporate AAC into the family's daily routine and activities, and reduce the demands on parents by preparing the AAC materials and programming the AAC system where possible.SLPs can provide ongoing support to school teachers to equip them with the necessary knowledge and skills to support the use of AAC in the classroom.

Efficacy of a novel augmentative and alternative communication system in promoting requesting skills in young children with Autism Spectrum Disorder in India: A pilot study

Background & aims: The study assessed the efficacy of a novel, child-friendly, socio-culturally sensitive, icon-based Augmentative and Alternative Communication (AAC) system called Jellow Communicator, in teaching requesting skills to young children with Autism Spectrum Disorder (ASD) in a special school in Mumbai, India. Jellow is a comprehensive AAC system with a lexicon and pictorial library designed using a participatory, user-centric design process. The content of Jellow has been developed bearing in mind the socio-cultural and linguistic diversity of India. Jellow is available in low-tech (flashcards, booklet) and high-tech (Android and iOS app and desktop application) versions. Methods: The quasi-experimental longitudinal study involved seventeen 3.5-12-year-old children with ASD with communication challenges. Children were taught to use the Jellow AAC system to request for preferred items, as part of their regular speech therapy sessions. Each child received one-on-one training sessions with a licensed speech therapist twice a week over a 3-month duration, with each session lasting around 20-30 min. A systematic training protocol adapted from the original Picture Exchange Communication System (PECS) was developed to train children to use the Jellow system, progressing from flashcards to the app version of Jellow. Behavioral training strategies such as modeling, least-to-most prompting, differential reinforcement, and behavior chain interruption were used to facilitate requesting behaviors. The speech therapist assessed children's developmental level across multiple domains at pretest and posttest. We coded 3 videos per child, i.e., one early, one mid, and one late training session each, to assess changes in children's stage of communication, spontaneous requesting abilities, level of attention during training trials, and average time to completion for requesting trials. In addition, caregivers filled out questionnaires to assess training-related changes in children's adaptive functioning levels as well as the psychosocial impact of the Jellow AAC system on children's quality of life. Results: Children significantly improved their stage of communication, and a majority of children transitioned from flashcards to using the Jellow app to request for preferred items. Children also increased the proportion of spontaneous requests over the course of training. Caregivers reported a positive perceived psychosocial impact of the Jellow AAC system on their child's self-esteem, adaptability, and competence. Conclusions: The findings from our pilot study support the use of the novel, socio-culturally adapted, Jellow Communicator AAC system for teaching requesting skills to young children with ASD who use multiple communication modalities. Future studies should replicate our findings with a larger group of participants using a randomized controlled trial design. Implications: This is the first experimental study to systematically assess the effects of an indigenously-developed comprehensive AAC system adapted to the sociocultural and linguistic landscape of India. Our study results provide support for the use of the cost-effective Jellow Communicator AAC system in facilitating requesting skills in children with ASD who use multiple communication modalities. Clinicians can use low-tech and high-tech versions of Jellow to promote communication skills in children with ASD.

Malaysian teachers' experience using augmentative and alternative communication with students

Teachers play an important role in the successful implementation of augmentative and alternative communication (AAC) for students with complex communication needs. The goal of this two-phase, mixed-methods study was to explore Malaysian teachers' use of, experience with, and perceptions about AAC. Phase 1 involved 252 teachers who completed a questionnaire that was aimed at collecting nationwide data about their use and overall perceptions of AAC. Phase 2 involved semi-structured interviews with 13 teachers who had experience supporting students who used AAC. Approximately half of the participants who completed the questionnaire knew about AAC and had used AAC with their students. Almost all of the participants had positive views of AAC though some misconceptions were reported. Most participants had limited knowledge about AAC that led them to experience difficulties supporting their students. Teachers were motivated to receive AAC-related training to enable them to use AAC more successfully with their students given the small number of SLPs in the country.

A systematic review of the barriers and facilitators to the provision and use of low-tech and unaided AAC systems for people with complex communication needs and their families

PURPOSE

Speech-language pathologists may introduce augmentative or alternative communication (AAC) systems to people who are unable to use speech for everyday communication. Despite the benefits of AAC systems, they are significantly underutilized by the people with complex communication needs. The current review aimed to synthesize the barriers and facilitators to the provision and use of low-tech and unaided AAC systems.  Materials and methods: Relevant literature was identified via a systematic search strategy. Included articles (n = 43) were evaluated using the Critical Appraisal Skills Programme. Qualitative framework analysis was then completed with reference to the International Classification of Functioning, Disability, and Health (ICF).  Results and conclusion: Most barriers and facilitators were coded as contextual factors within the ICF. Of most prominence were environmental factors, including attitudes of and supports provided by professionals, family members, and the society at large. Themes were also identified which related to the personal factors, including the user's own attitude, socioeconomic status, and culture. Beyond these contextual factors, the remaining codes related to body functions such as cognition and movement. There are numerous barriers to the provision and use of low-tech and unaided AAC systems, which may contribute to the inadequate use of these systems by people with complex communication needs. Suggestions for reducing these barriers are presented with regards to the person with complex communication needs, their family, and the professionals involved in their care. Implications for Rehabilitation AAC systems can reduce participation restrictions for people with complex communication needs. The provision and use of AAC systems is influenced by environmental factors, personal factors, and features of a person's body function. SLPs may need to collaborate with a large multidisciplinary team to successfully introduce AAC systems. SLP, teaching, and nursing students require theoretical and practical experience in AAC throughout their training to enable the provision and use of these systems.
